能源地下结构研究及应用进展

Research and application progress of energy underground structures

  • 摘要: 能源地下结构是将热交换管埋设在建筑基础构件和地下结构物中,兼具承载及换热功能的结构形式,在有效节省宝贵且不可逆的地下空间资源的同时,还能充分利用非碳基的连续稳定、安全清洁的地热能资源,这比传统的地源热泵更具优势。系统总结了能源地下结构的概念、优势、国内外研究及应用进展,重点阐述了能源隧道、能源桩(能源锚杆)、能源地下连续墙和能源综合管廊4种目前常见能源地下结构的现状。将地源热泵系统与煤矿巷道等矿区建设相结合,既能够对地热能资源进行综合利用,还可有效解决传统深部采矿掘进作业时的高温热害及寒区煤矿巷道的保温防冻难题,具有环保、低碳、节能、高效的显著优势,是实现绿色矿井建设及碳达峰碳中和目标的有效途径,可产生显著的经济效益、环境效益和社会效益。然而,现有能源地下结构的研究模型均有其适用性和局限性、研究结果与实际工况存在较大偏差、能源地下连续墙和能源综合管廊研究较少等是当前存在的主要问题,对于能源地下结构的研究工作应结合工程实际情况,并尽可能考虑所有因素对结构工程的影响,以期提升研究成果的精度和水平;此外,对煤矿巷道等矿区建设中运用能源地下结构的可行性和前景进行了探讨,在能源地下结构的基础上,进一步综合太阳能、风能等非碳基清洁能源构建复合能源利用系统也是值得尝试的思路;同时,还对能源地下结构在抗(减)震、抗爆和防火等方面的防灾减灾设计给出建议,可为能源地下结构及其在绿色矿井建设方面的研究、应用与发展提供参考。

     

    Abstract: Energy geostructure refers to a type of structure equipped with heat exchange pipe in the building foundation element and the underground structure, which has the functions of load bearing and heat exchange. It not only effectively saves the valuable and irreversible underground space resources, but also makes full use of the non-carbon based continuous, stable, safe and clean geothermal energy resources, thus having more advantages than the traditional Ground Source Heat Pump (GSHP). Herein, the concept, advantages, research and application progress of energy geostructure at home and abroad were systematically summarized. Moreover, the current situation of four common energy geostructures, namely energy tunnel, energy pile (energy anchor), energy diaphragm wall and energy utility tunnel, were emphatically described. The combined construction of GSHP system and mining areas, such as the coal mine roadway, could not only make comprehensive use of geothermal energy resources, but also effectively solve the problems of high temperature hazard in traditional deep mining excavation, as well as heat preservation & anti-freezing of coal mine roadway in cold areas. Thus, it has the obvious advantages of environmental protection, low carbon, energy saving and high efficiency, and thereby becomes an effective way to achieve the green mine construction and the goals of “carbon peaking and carbon neutrality”, capable of producing significant economic, environmental and social benefits. However, the current research models of energy geostructures have their own applicability and limitation, with the main problems of large deviation between the research results and the actual working conditions, and few researches conducted on energy diaphragm wall and energy utility tunnel. In terms of research on energy geostructures, reference should be made to the actual engineering situations, and the influence of all factors on structural engineering should be considered as far as possible, so as to improve the accuracy and level of the research results. In addition, the feasibility and prospect of using energy geostructures in construction of coal mine roadway were discussed. On the basis of energy geostructures, it is also a good idea to try to build a composite energy utilization system by further integrating the non-carbon based clean energies, including the solar and wind energies. Meanwhile, the suggestions were given for the design of hazard prevention and mitigation of energy geostructures in view of earthquake resistance (reduction), explosion resistance and fire protection, which could provide reference for the research, application and development of energy geostructure and its application in green mine construction.
